How To Find A Replacement Filter For your Swimming Pool Or Spa

#1 Measure the outside diameter of the cartridge in inches (+ or - 1/16")

#2 Measure the overall length of the cartridge in inches (+ or - 1/16"), including the end caps. You
don't need to include any handles or strings. A more accurate measurement can be obtained by measuring
through the center hole of the pool cartridge when possible

#3 Make a note of the (OEM) original manufacturer model number of the replacement cartridge

#4 Take note whether or not there is a center core (PVC pipe in the center) and also count the number of pleats (+ or - 2)
